COMBINED DAMPER-REGULATOR AND VENTILATOR.

SPECIFICATION forming part of Letters Patent No. 656,895, dated August 28, 1900.

Application fil d December 20, 1899. flerial No. 740,989. (N 0 model.)

To all whom it may concern.-

Be it known that I, FREDERICK L. KING, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in a Combined Damper-Regulator and Ventilator, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to an improved construction of a damper-regulator and ventilator wherein I employ a ventilating-pipe or ventilator for withdrawing cold air and heavier or impure gases from the lower portion of the apartment, an outlet-flue leading from a heater, into which flue said ventilator discharges, and a single damper located at the lower junction of said flue and ventilatorpipe, said damper having one end of a link attached thereto, the other end of said link being pivotally attached to an arm operative in unison with a handle exteriorly located, said arm and the shaft or pivot to which it is attached forming a crank-shaft, the arm extending upwardly and serving with the link to hold the damper in a closed or upright position when the arm is thrown to one side of its pivot, said damper being opened when the arm is moved in the opposite direction.

It further consists of novel details of construction, all as will be hereinafter fully described, and particularly pointed out in the claim. V

Figure 1 represents a side elevation of a combined damper -regulator and ventilator embodying my invention, the damper being shown in open position. Fig. 2 represents a vertical sectional view of certain of the parts seen in Fig. 1, the damper being shown in position to close the ventilator. Fig. 3 represents a side elevation of a modified construction somewhat similar to Fig. 1, but showing the damper turned so as to close the outlet-flue from the heater.

Similar letters of reference indicate corre sponding parts in the figures.

Referring to the drawings, A designates a heater of any suitable construction, and B the outlet-fiuetherefor.

C designatesa ventilator-pipe which is suitably supported upon tbe floor D of the apartment and has its lower extremity E slightly raised above said floor, whereby the cold air or heavier or impure gases can readily enter said lower end.

F designates a damper which is pivoted at G in any suitable manner and has connected thereto one end of the link H, the other end of said link being pivoted to the arm J, which is operated by the shaft K, having the handle K, which is located exteriorly to the ventilator and outlet-flue.

The operation is as follows: When the parts are in the position seen in Fig. 1, it will be apparent that the heated products of combustion pass through the heater A out the flue B in the direction of the arrows, a draft being created thereby which draws into the ventilator O, at its lower portion E, the cold air and heavier or impure gases, which are normally at or near the lower portion of the room or apartment, the course of said gases during their egress being indicated by the arrows in the ventilator '0. When the damper is in the position seen in Fig. 2, it will be apparent that no draft can pass through the ventilator-pipe G into the flue B, the latter conveying the soot and products of combustion unimpeded to the desired point without creating a suction or draft in said ventilator-pipe. When the parts are in the position seen in Fig. 3, the damper F has closed the flue B; but by reason of the draft the cold or impure air can readily pass through the ventilator-pipe G and out through the line B, amaximum quantity of heat units being retained within the heater.

It will beevident that by the employment of a single damper pivoted in the manner described and having an end of the link H pivotally attached thereto, the other end of said link being attached to the arm J of the shaft K, the damper can be readily moved or set by a very slight movement of said handle, and it will be further apparent that the use of said link and arm enables me to locate the handle K at one side of the damper and in the ordinary position. By the use of the link and arm and their adjuncts I produce a cheap and simple construction wherein the cost of manufacture is reduced to a minimum.

It will thus be seen from the foregoing that by my invention I have produced an efiective appliance which can be readily assembled and is not liable to get out of order.

Having thus described my invention, What I claim as new, and desire to seen re by Letters Patent, is-

A flue, a damper pivoted at the bottom. thereof, a crank-shaft, the radial arm of which extends upwardly, and a connecting-link pivl0 otally attached to the damper and to said upwardlyextending arm, said parts being so constructed and arranged that the damper is closed and held closed When the arm is thrown to one side of the pivotal shaft and is opened when the arm is moved in the opposite diree- 15 tion.
